Day/Night Movie Module?

[Kolmain 6]

Is there anyway that I can alternate between the day and night movie effects modules depending on the time?

Can't help with the Movie Modules but here's a brilliant way to find out if it's dark...was just looking this up yesterday myself. Thanks to Carl Gustaffa.

Hope it helps.

You can change the ppEffects any time during the mission.

Movie Day:

"colorCorrections" ppEffectAdjust [1, 1.02, -0.005, [0.0, 0.0, 0.0, 0.0], [1, 0.8, 0.6, 0.65],  [0.199, 0.587, 0.114, 0.0]];
"colorCorrections" ppEffectCommit 0;
"colorCorrections" ppEffectEnable true;

Movie Night:

"colorCorrections" ppEffectAdjust [1, 1.15, 0, [0.0, 0.0, 0.0, 0.0], [0.5, 0.8, 1, 0.5],  [0.199, 0.587, 0.114, 0.0]];
"colorCorrections" ppEffectCommit 0;
"colorCorrections" ppEffectEnable true;

so heres the code

X_fnc_SunElev = {
/*
	Author: CarlGustaffa

	Description:
	Returns the suns altitude for current day and hour of the year on any island (whos latitude may differ).

	Parameters:
	None needed.

	Returns:
	Suns altitude in degrees, positive values after sunrise, negative values before sunrise.
*/
private ["_lat", "_day", "_hour", "_angle", "_isday"];
_lat = -1 * getNumber(configFile >> "CfgWorlds" >> worldName >> "latitude");
_day = 360 * (dateToNumber date);
_hour = (daytime / 24) * 360;
_angle = ((12 * cos(_day) - 78) * cos(_lat) * cos(_hour)) - (24 * sin(_lat) * cos(_day));
_angle
};

but im nto sure how to implement it? how do i get the return?

[twirly 11]

You include it as a function in a script like this....

X_fnc_SunElev = {
/*
	Author: CarlGustaffa

	Description:
	Returns the suns altitude for current day and hour of the year on any island (whos latitude may differ).

	Parameters:
	None needed.

	Returns:
	Suns altitude in degrees, positive values after sunrise, negative values before sunrise.
*/
private ["_lat", "_day", "_hour", "_angle", "_isday"];
_lat = -1 * getNumber(configFile >> "CfgWorlds" >> worldName >> "latitude");
_day = 360 * (dateToNumber date);
_hour = (daytime / 24) * 360;
_angle = ((12 * cos(_day) - 78) * cos(_lat) * cos(_hour)) - (24 * sin(_lat) * cos(_day));
_angle
};

[color="Red"]_sunangle = [] call X_fnc_SunElev[/color];

hint format ["Angle of the sun is %1",_sunangle];

..or you can make a separate ".sqf" for it and also call it as a function.

In which case you would preprocess the function by including this line in your "init.sqf" in your mission folder.

init.sqf:-

X_fnc_SunElev = compile preProcessFile "X_fnc_SunElev.sqf";

Now the function itself....

X_fnc_SunElev.sqf:-

	/*
	Author: CarlGustaffa

	Description:
	Returns the suns altitude for current day and hour of the year on any island (whos latitude may differ).

	Parameters:
	None needed.

	Returns:
	Suns altitude in degrees, positive values after sunrise, negative values before sunrise.
*/
private ["_lat", "_day", "_hour", "_angle", "_isday"];
_lat = -1 * getNumber(configFile >> "CfgWorlds" >> worldName >> "latitude");
_day = 360 * (dateToNumber date);
_hour = (daytime / 24) * 360;
_angle = ((12 * cos(_day) - 78) * cos(_lat) * cos(_hour)) - (24 * sin(_lat) * cos(_day));
_angle
};

Then call the function the same way as above :-

_sunangle = [] call X_fnc_SunElev;
hint format ["Angle of the sun is %1",_sunangle];

Hope that helps in some way.

Clarity

[Kolmain 6]

so using this

_sunangle = [] call X_fnc_SunElev;

will return _sunangle as the angle, pos day negative night? so jsut check if and then?

EDIT: Goona try this

X_fnc_SunElev = {

Roger on that!

[demonized 20]

this will give different values dependig on time of year, in dec i get darkness ca at -3,75.

in june i get darkness at ca -10.

Now the script itself only determines sun elevation and not darkness so script works as intended ofc, but there is always light quite awhile after sundown, as in RL.

But i want to be able to determine darkness.

Accurate determination of darkness is not easily acessible, but can ofc be tested and set to whatever value wich coresponds with your missions date.

so for december i choose -4 as elevation value to determine darkness.

Anyone got a solution to this so it can be used all year without predefining value for current date?

Also its higly dependant on day of month and weather. so values are very fluid.

Was thinking of maybe just hardcode the 365 days values into my scripts, but that seems like an never ending task now with at least 1000+ different values.
